HAMMERHEAD SHARK FACTS
|Scientific name:||Sphyrnidae (Sphyrna mokarran – Great Hammerhead)|
More About Hammerhead Sharks
There are nine species of hammerhead sharks worldwide. The hammerhead with its strangely shaped head is somewhat of a mystery although scientists have recently discovered that the odd shape improves their vision, making them excellent hunters.
The Great Hammerhead, the largest of the hammerheads, can reach a length of 25 feet, almost the size of a Great White shark. Hammerheads are known for their schooling behavior and consume a variety of prey including rays, other sharks, fish, squid, and crustaceans
There are nine species of hammerhead sharks worldwide in the family Sphyyrnidae. The Great Hammerhead is the largest reaching a length up to 20 feet and weighing as much as 1,000 pounds. These sharks are named for the unusual shape of their head which is flattened forming two lobes which extend out to the side.

They are found in temperate and tropical regions around the globe and are found in both nearshore and offshore waters usually between 1-300 meters in depth. Hot spots include Colombia, Costa Rica (Cocos Island), and Hawaii.
Of the nine species found worldwide, seven of them have been evaluated by the IUCN Red List. The Great Hammerhead (Sphyrna mokarran) is listed as Endangered with a decreasing population.
Like other sharks around the world, they are under threat from bycatch in commercial fisheries as well as shark-finning, the practice of capturing sharks and removing their fins for commercial purposes.
The Scalloped Hammerhead (Sphyrna lewini) is also listed as Endangered. Other species are in decline or their population trends are currently unknown.
